My Sprint 2 transformer is DOA. I would like to just put a switcher in it's place. Can someone direct me where I have to attach the voltage too? I looked on the PCB the there are no labled test points that I noticed.

Do you mean the onboard power supply is nonfunctional? Lots of things go wrong including bad caps (the two 16v 8000uf sausages by the edge connector) and the TO3 LM323 5v 3a regulator often go bad.

Not too hard to fix. You might be able to hook up a switcher if you removed the LM323 regulator and wired it in there but I think the power resistor to the 10v unregulated supply might prevent using this method - not sure though.
